SIGNAL-PIPE SUPPORT.

Specification of Letters Patent.

'Patented Apr. 2, 19in.

Application ledMarch 9, 1916. Serial No. 83,036.

To all whom may concern.' Be it known that I, FREDERICK FRENCH, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Signal-Pipe Supports, of which the following is a specification, reference being had therein to the accompanying drawings.

Railway signal systems, particularly' of the interlocking typev as now universally used, especially in large railroad yards, include what is known in the art as pipe carriers for the lead outs of the signals and on account of the large number of signals which may be controlled from a single tower there is necessarily a large installation of pipe carriers and lead outs. It is the present practiceto make these lead outs of rigid tubing or pipe and to support the same upon Vpipe carriers having various kinds of foundation. The lead outs are generally disposed in parallelism and from time to time branch off to signals, consequently the tubing or pipes used as lead outs are of certain lengths and must be connected together to form a lead out of a desired length. In consequence of such installation there are necessarily waste sections or pieces of tubing or pipe, which either become scrap or'are used in completing a lead out of desired length.

`A multiplicity of lead outs necessitates one or more foundations and it has been the practice to connect these foundations by base plates for the pipe carriers. As the number of foundations depend upon the number of lead outs, there is nospecified distance between the foundations and naturally there must be on hand a stock of base plates of various lengths which will permit of the base plates being connected Afrom one foundation to another. The base plates are often in the form of malleablel iron plates, channel bars or even wood sills. Owing to various lengths of base plates or sills being required, there is necessarily a large stock of material Von hand and as no two'signal installations are alike, special specifications are necessary.

To utilize scrap or shortlengths or lead out pipes as supports for carriersand `to provide a standard support for such pipes which will be applicable to any foundation,

Ais the paramount object of my invention. By utilizing the tubing or'pipe in conjunction with a standard support, I eliminate a varied stock of signal materiahsuch as different. lengths of base plates or sills, besides retaining the strength and rigidity of lead out pipes in forming practically an indest'ructible fabricated framework upon which pipe or wire carriers, as well as other signal appurtenances may be mounted.

Other features of my invention will appear as the nature of my invention is better understood, and refeience will now be had to the drawings, wherein Figure l is a front elevation of my improved support for the pipe carriers of signal lead outs;

Fig. 2 is a plan of asupport with pipe carriers removed therefrom;

Fig. 8 is an end view of the same, showing hook bolts holding a pipe carrier on a support, and

Fig. t is a perspective View of a detached support. y

In the drawing, 1 ldenotes foundation blocks or piers of a conventional form commonly used when installing lead outs of signals, said piers having side walls thereof provided with recesses or sockets 2 for the angle heads or hooks 3 of bolts or tie rods i employed for anchoring lead out supports upon a pier. Alead out support in accordance with my invention comprises parallel base bars 5 connected, intermediate the ends thereof by transverse parallel upright cleat members 6 carrying parallel dished or concave rest members 7 for carrier holders or tubular supports 8.

The base bars 5 are comparatively dat and are disposed in close proximity with said bars of a length to protrude beyond the upper end of a pier. The protruding ends of the base bars 5 form slots or bifurcations to receive the upper ends of the bolts or tie rods t and with nuts 9, or other hold fast devices on the upper `ends ofv the bolts or tie rods @the base bars 5 are anchored relative to a pier. The slot or space between the 'base bars 5 permits of the base bars being shifted on top of the pier relative to the bolts or tie rods 4L, consequently thevbase bars 5 can be adjusted relative to a pier and have no defined position until anchored by the bolt or tie rods 4.

Transverse cleat members 6 have the lower edges thereof in the same plane as the bottom faces of the base bars 5 and said cleat members coperate with the base bars in obtaining a bearing upon the pier 1 which is well distributed upon the top of the pier. The cleat members 6 are farther spaced apart than the base bars and' support the rest members 7 in a horizontal plane above the pier 1. The restmembcrs 7 are ofless length than the base bars, but are Well balanced relative to said bars and the cleat members 6 to alford a substantial rest for. the holders or tubular supports 8. These holders o r tubular supports are made of lengths oirpiecesV of a pipe ordinarily used as lead( outs of a signal, and. said holders provi dea substantial rest forthe base pieces or feet 10 of PDecarriei-s 11. The pipe carriers are of` the ordinary and Well. known type and are retained in engagement with the holders 8-r and the rest members 7 by hook bolts. 12 some ot which engage under the rest members?- While others simply engage the holders 8, as best shown. in Fig. 1. Thehook bolts-125prevent vertical as Well as lateral displacements ofthe pipe carriers 11 and as said hook bolts are detachable rela tiveto,the pipe canriers 11, saidpipe carriers can be shifted laterally ofu theholders 8 and properly assembled for carryinga desired number ofy pipe. lead outs.

When two or more foundations or piersl are. required for supporting a large number of lead outs, the holders 8 can extend from one, pier tol another, as shown in Fig. 1, thereby tying the piers or foundations togethenin suchl ai manner that pipe carriers onthe holders 8 will be maintained inproper relation, even though some of the foundationsor piers should be injured or deteriorete in advance of, others.

Besides the. holders affording a substantial bearing or support for the pipe carriers 11, and, tying the foundations or piers to gether, asjust; mentioned, said. holders, particularly inconnection with a single foundation or pier, constitute convenient handA grips for easily setting a previo-usly molded or formed. foundation block or pier and for carryinga series of; pipe carriers prior to,

connecting the same to a pier. Asthe'holdersvcan, be" clamped between the rest members 7l` and the base pieces or feet of the pipe carrier 11, it is possible to use the short lengths of` pipes. for the holders and have the confronting ends of the pipes meet on the rest members 7 for, instance, as shown at the left hand end of Eig. 1. This allows scrap ends of` pipeto be utilized as holders especially when, only one or two pipe carriers are to be mountedupon a pier.

From the foregoing it Will be noted that a support, such as illustrated in Fig. 4, is applicable to the top of a pier, irrespective ofithe length of,` the holders 8 to be supported thereby, consequently the support shown in'V Fig.. et. becomes a. standard article and eliminatesplates and sills. of; various sizes as fheretofor'e used. When installing a sig- Leens?? nal system the pipes for the mechanically interlocking lead outs are on hand to be cut and fitted together andJ it is only necessary to uselengxths or scrap ends of these pipes as holders for the pipe carriers. By reducing the stool; heretofore maintained for the installation and repair of signal systems there is not only a monetary saving, but the annoyance of handling and maintaining a record of a varied stock` is` obvi` ated, and the essential` elements for signal lead outs reduced` to a minimum.

Vilhile in the drawingsthere is illustrated a prcferrmlv embodiment of my invention, it is to be understood that the structural. elements are susceptible.to.suclt change in. sirve,
